Welcome back Ama — been a while! Let's pick up where you left off. Here are the answers to Question One: Step 1: Analyse the possible type of condition. The student is 19 years old and has experienced an absence of menstruation for 8 months, implying she has previously menstruated. This indicates secondary amenorrhoea. Secondary amenorrhoea Step 2: State TWO (2) causes of her condition. Based on the provided history, two causes of her condition are: • Significant weight loss • Intense daily exercise 1. Significant weight loss 2. Intense daily exercise Step 3: Explain the underlying pathophysiology. The combination of significant weight loss, intense exercise, and high stress can lead to hypothalamic amenorrhoea. This occurs due to a disruption of the hypothalamic-pituitary-ovarian (HPO) axis, specifically a reduced pulsatile release of Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus. This, in turn, decreases the secretion of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) from the pituitary, leading to insufficient estrogen production by the ovaries, anovulation, and consequently, the absence of menstruation. Step 4: Identify THREE (3) key features from her history that support your diagnosis. Three key features from her history that support the diagnosis are: • Absence of menstruation for the past 8 months • Significant weight loss • Intense daily exercise 1. Absence of menstruation for the past 8 months 2. Significant weight loss 3. Intense daily exercise What's next? Send 'em! 📸
